Zhang Tie had fought and bled in Selnes Theater of Operations. He had a lot of memories over there. At that time, Zhang Tie served as the only human air cavalry in the Selnes Theater of Operations. Although it looked very honorable, he was actually a cannon fodder. Finally, he was betrayed by b*stards of Three-eye Association among humans and almost lost his life like what the other small figures were destined to face on the battlefield.
Whereas, Zhang Tie didn't regret what happened in Selnes Theater of Operations. He would still return to the Selnes Theater of Operations and contribute his strength to the holy war as a human fighter as long as he was demanded.
However, Zhang Tie was not the same one in Selnes Theater of Operations anymore.
When in Selnes Theater of Operations, Zhang Tie was just a LV 10 fighter; however, now, Zhang Tie had already become an earth knight who was unrivaled on many subcontinents.
